ARM.

SPECIFICATION forming part of Letters Patent No. 560,570, dated May 19,1896. Application filed October 23,1895. $erial No. 566,644. (No model.)

, skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in toy arms or devices forproducing sounds in imitation of the explosion of cannon and otherfirearms.

It is proposed to make the arm in form to imitate the general appearanceof a pistol, a shoulder-gun, or a cannon, although the outwardappearance constitutes no part of the invention, the main object ofwhich is to produce explosive sounds by harmless means and in aneconomical manner.

The invention consists in certain constructions and combinationshereinafter described and claimed.

In the drawings forming a part of this specification, Figures 1, 2, 3,and 4 are sections of different forms or applications of my invention.Fig. 5 is a front elevation of the cappiece shown in Figs. 2 and 4. Fig.6 is a detail of valve shown in Fig. 3, and Fig. 7 is an elevation ofthe cap-piece shown in Fig. 1.

In Figs. 1 to 4 an air compressor or pump is shown, consisting ofcylinder A, piston B, and operating-handle O. In these figures I haveshown a pistol grip or handle D connected with a pump-cylinder forconveniently holding the device at arms-length to imitate the operationof pistol-shooting. Obviously a shoulder-piece or butt in imitation of amusket or rifle may be substituted for the pistolgrip and the device maybe mounted on trucks in imitation of a piece of field-artillery. At themouth or forward end of the cylinder shown in Fig. 1 I provide a seatfor the gasket land detachably connect with the cylinder a ring or a cap2, having a hole or passage through it, as shown. The object of the ringor cap is to support a sheet of paper or other material 3 across themouth of the cylinder. The ring is clamped or held against the paper andgasket by any suitable device. The

means shown in this application consists of yokes 4 4, pivotallyconnected with the cylinder and set-screws 5 5, the yokes and screwsconstituting clamps to press the ring or cap against the interposedpaper and hold it firmly in place and prevent leakage of air. In thisform a sounding toy of some efficiency is produced. To operate thedevice so far described, the paper being held over the mouth of thecylinder and the piston withdrawn, the piston is forced rapidly forwardthrough the cylinder. As in a pop-gun, the compressed air bursts thepaper and a loud explosive sound is produced.

To augment the efficiency of the instrument and increase the sound, Iprovide a lid or cover 6 to sustain the paper until great pressure isaccumulated in the cylinder and then suddenly release the support,whereupon a loud explosive report is produced. The means for holding andreleasing the lid or cover consists of a movable stop 7, a trigger S,and a spring 9.

Another Way of operating the device shown in Fig. 1 is to omit the lidor leave it free, then compress the air to just within the limit of thestrength of the paper, and then impart a sudden impulse, as by a blow,to the piston. This mode of operation is facilitated by providing ashoulder or stud 10 on the pistonrod and a stop or detent 11 to hold thepiston in a forward position under tension, as shown in Fig. 1, when ablow on the handle 0 will cause the paper to burst suddenly.

In the form shown in Figs. 2, 3, and 4 I have provided an enlargedair-chamber 12, having a check-valve 13, and have also shown a tubularprojection 14 in the nature of a pistol-barrel. By means of this glandor enlarged chamber a considerable volume of air may be compressed toany desired tension sion and sound.

In Fig. 2 the means for supporting the paper consists of a plug 15,having an annular groove with which the movable stop 7 engages to lockit in position during the process of compressing the air. In this formand in the form of the invention shown in Figs. 3 and 4 the toy servesto imitate the sound produced by explosive compounds, and also serves todischarge wooden or other light projectiles in further imitation of areal firearm.

and then suddenly released to produce explo- The form shown in Fig. 3has the air compressor or pump, the gland or enlarged chamber, and avalve 16, the valve being between the gland and the mouth of the deviceto hold the compressed air within the gland and out of contact with thepaper until released by trigger-operated connections, as shown.

Fig. 4: shows a way of using my device to some extent for amusementwithout employin g a disk of paper. In this method of operation a lightplug in the form of a projectile with a gasket 17 and groove is used andgives a report somewhat of the character of a popgun.

Itis observed that the efficiency of my invention depends on the factthat the fabric or substance which steps or closes the mouth of thedevice is held in position with force and the fact that the stopper issuddenly released or gives way to permit the expansion of the air.

Having now described my invention, what I claim is- 1. In a toy arm orgun, the combination of a chamber adapted to be filled with compressedair, means for holding a sheet of fabric or other material over a mouthof said chamber, a cover or support to sustain the surface of thefabric, and mechanism for releasing the surface-support.

2. In a toy arm or gun, the combination of ftG]1 t1llbOl,'2t11air-compressor discharging into said chamber, a check-valve to retainair in said chamber, means for holding a sheet of fabric or othermaterial over the mouth of the chamber, a movable support for sustainingthe paper opposite the mouth, and means for releasing the paper-support.

3. In a sounding toy, the combination of a chamber, means for holdingcompressed air in the chamber, means for holdinga sheet of fabric orother material in front of the mouth of the chamber, and mechanism forreleasing the compressed air, for producing sound.

4:. In a sounding toy, the combination of a chamber, an air-co1npressordischarging into said chamber, means for holding the compressed air inthe chamber, means for ho1ding a sheet of fabric or other material infront of the mouth of the chamber, and mechanism for releasing thecompressed air, for producing sound.

5. In a sounding toy, the combination of a chamber, an air-compressordischarging into said chamber, means to hold the compressed air in thechamber and means for holding a sheet of fabric or other material infront of the mouthof the chamber, for producing sound.

In testimony whereof I affix my signature in the presence of twowitnesses.
